The new Synergistic Research BLUE fuses ....

New SR BLUE fuse thread ...

I’ve replaced all 5 of the SR BLACK fuses in my system with the new SR BLUE fuses. Cold, out of the box, the BLUE fuses stomped the fully broken-in SR BLACKS in a big way. As good as the SR BLACK fuses were/are, especially in comparison with the SR RED fuses, SR has found another break-through in fuses.

1. Musicality ... The system is totally seamless at this point. Its as if there is no system in the room, only a wall to wall, front to back and floor to ceiling music presentation with true to life tonality from the various instruments.

2. Extension ... I’ve seemed to gain about an octave in low bass response. This has the effect of putting more meat on the bones of the instruments. Highs are very extended, breathing new life into my magic percussion recordings. Vibes, chimes, bells, and triangles positioned in the rear of the orchestra all have improved. I’ve experienced no roll-off of the highs what so ever with the new BLUE fuses. Just a more relaxed natural presentation.

3. Dynamics ... This is a huge improvement over the BLACK fuses. Piano and vibes fans ... this is fantastic.

I have a Japanese audiophile CD of Flamenco music ... the foot stomps on the stage, the hand clapping and the castanets are present like never before. Want to hear natural sounding castanets? Get the BLUE fuses.

4. Mid range ... Ha! Put on your favorite Ben Webster album ... and a pair of adult diapers. Play Chris Connor singing "All About Ronnie," its to die for.

Quick .... someone here HAS to buy this double album. Its a bargain at this price. Audiophile sound, excellent performance by the one and only Chris Connor. Yes, its mono ... but so what? Its so good you won’t miss the stereo effects. If you’re the lucky person who scores this album, please post your results here.

Overall impressions:

Where the RED fuses took about 20 hours to sound their best, and the BLACK fuses took upwards of 200 hours of total break-in, the BLUE fuses sounded really good right out of the box ... and that’s without doing anything about proper directional positioning. Not that the BLUE fuses don’t need breaking in, they do. The improvement continues through week three. Its a gradual break-in thing where each listening session is better than the last.

Everything I described above continues to break new ground in my system as the fuses continue breaking in. Quite honestly, I find it difficult to tear myself away from the system in order to get things done. Its truly been transformed into a magical music machine. With the expenditure of $150.00 and a 30 day return policy there’s really nothing to lose. In my system, its like upgrading to a better pre amp, amp, CD player or phono stage. Highly recommended.

Kudos to Ted Denney and the entire staff at SR. Amazing stuff, guys. :-)

PS: If you try the SR BLUE fuses, please post your results here. Seems the naysayers, the Debbie Downers and Negative Nellie’s have hijacked the original RED fuse thread. A pox on their houses and their Pioneer receivers.

Again, I will post that the most conservative, non-tweaking audio engineer/equipment manufacturer who heard the difference between "new" Littlefuses and my SR Blue fuses, immediately went home and installed circuit breakers where his fuses were located at (we have the same amps).  He has no tweaks in his audio system which sounds superb.  He hates any liquid treatment on contacts including TC although he will never try it.  I thought the circuit breakers made a tremendous difference from the Littlefuses he previously had installed.

So, if the difference between fuse quality and circuit breakers were not so obvious, an expert in audio engineering would not have changed his equipment.  But he heard it and he did it.

I’ve heard of people like that before. 😛

A definition of an expert. Someone who who used to be a squirt under pressure. Another definition of expert. Someone fifty mikes from home in a cheap suit and carrying a suitcase. 😃

Most "experts" in audio engineering I know don't give a hoot about silly magical tweaks with no basis in reality, and if you can find one who does, well, so what. All are welcome in Wonderland…I remain a believer in Littelfuse stuff because since I'm a wealthy man (!), I can afford the 2 bucks. I can say there's a lot of evidence that breakers "sound" better than fuses, but there isn't, so I won't.

The ’blowtorch’ thread over at DIY audio was and is full of audio designers. Fuses and circuit breakers were and are topics of discussion.

Circuit breakers are preferred due to their ’least’ level of sonic interference.

Fuses end up being the item of choice due to the manufacturers, not the designers. Fuses and fuse holders are much less expensive than circuit breakers.

Since one has never heard the amplifier they own with circuit breakers instead of fuses..the question remains...but as a question that is non existent, unrealized, unasked.

Thus the manufacturer saves the money or costs of 4/5/etc circuit breakers of optimum quality, per standard amplifier, as they only have to buy and install fuses and fuse holders. Fuses...which don’t have failure modes like circuit breakers might....and any circuit breaker problems (ie, unknowns, and we don't want unknowns) stay off the manufacturer's plate of after sale issues.

Gosh, one can’t help wondering what kind of reception fuse directionality gets over on the illustrious Blowtorch thread. Assuming it even comes up. 🤡 Uh, what’s it up to, 3 Million posts?
